UFC heavyweight champion Francis Ngannou has opened up as a massive betting favorite for a potential rematch against Derrick Lewis.

Ngannou is currently involved in a very public fight negotiation with the UFC and former light heavyweight kingpin Jon Jones. Both Jones and Ngannou want the fight, but the UFC is having trouble coming to financial terms with Jones. Instead, the promotion is now floating a potential rematch between Ngannou and Lewis instead. On Monday, ESPN’s Ariel Helwani reported that the UFC has offered Ngannou the rematch with Lewis for UFC 263 in June, but the heavyweight champion turned it down due to issues with timing. It also seems likely that he wants to see if the UFC can get the fight with Jones done first, as well.

Either way, with Ngannou vs. Lewis now being floated around as a potential matchup, the sportsbooks have released the opening odds for the fight. Despite the fact that Lewis won the first meeting between these two at UFC 226 three years ago by unanimous decision in a big upset, the sportsbooks have once again opened up Ngannou as a big favorite here.
